In comparison to another environment how much plant material do coral reefs produce?

How are coral reefs formed?
Coral reefs are formed from colonies of small animals called polyps and one of the worlds most spectacular ecosystems.
What particular conditions are needed for the growth of reef building corals?
Warm sea temperatures, with an average water temperature above 18•C , and are most productive in stable water temperatures between 22 and 25•C.
High salt levels -close to the open sea
Clear water -sediment rich water will block the light and smother corals.
What percentage of the worlds fish species do Coral Reefs contain?
They have been called the gardens of the sea because of the variety of plant and animal life they contain.

In shallow water either side of the equator, generally away from the equator.
